Answer:
40 cm³
Step-by-step explanation:
To solve this problem, it's easiest to imagine this figure as a half of a whole retangular prism. You can find the volume of that rectangular prism and divide the answer by 2. So, to find the volume, multiply each dimension by the others.
5 · 8 · 2 = 80
The volume of the rectangular prism we imagined is 80 cm³. So to find the volume of the original figure instead, divide this answer in half, to find 40 cm³. The answer is B, 40 cm³. Be sure to use the cubed symbol, '³' , to show volume. Hope this helps ^^ Good luck
